Description

TECHNICAL FIELD

[0001] The application relates to the technical field of connecting structures, in particular to a hinge cover. BACKGROUND

[0002] At present, a hinge, also known as a hinge, is a mechanical device used to connect two solids and allow relative rotation between the two. The hinge can be composed of movable components or of foldable materials.

[0003] The existing hinge is generally made of ordinary alloy steel through ordinary forming process, and the mounting screw is directly exposed outside after the hinge is completed, and the threaded hole for mounting the screw is also exposed outside.

[0004] The existing technical solution has the following defects: the screw is exposed outside, which is not beautiful and is easy to be oxidized. Utility model content

[0005] The application provides a hinge cover to improve the appearance of the hinge and slow down the oxidation speed of the screw.

[0006] The above technical purpose of the application is achieved through the following technical scheme:

[0007] A hinge cover comprises a pair of hinges, which are movably connected to each other through a hinge shaft, and a cover plate covering the upper surface of the hinge. A first adhesive layer is arranged between the cover plate and the upper surface of the hinge to connect the hinge and the cover plate.

[0008] By adopting the above scheme, the cover plate covers the upper surface of the hinge, thereby shielding the screw, so that the upper surface of the hinge is smooth. This not only maintains the appearance of the hinge, but also isolates the screw from direct contact with air within a certain range, thereby slowing down the oxidation speed of the screw.

[0009] Further, a side cover plate is arranged on the periphery of the hinge and fixedly connected with the cover plate. A second adhesive layer is arranged between the side cover plate and the hinge to connect them.

[0010] By adopting the above scheme, the side cover plate covers the periphery of the cover plate, so that the cover plate and the side cover plate form an integral whole, increasing the appearance of the hinge surface.

[0011] Further, a circular arc is arranged on one side of the cover plate close to the hinge shaft.

[0012] By adopting the above scheme, the circular arc makes the cover plate more closely fit the side wall of the hinge shaft.

[0013] Further, the lower surface of the cover plate is provided with a connecting pin, which is inserted into a threaded hole in the surface of the hinge, and the connecting pin is in interference fit with the threaded hole.

[0014] By using the above scheme, the connecting pin is provided, so that the connecting pin can be connected with the threaded hole, and because the connecting pin is connected with the cover plate, the connecting area of the cover plate and the surface of the hinge is increased, so that the connection of the cover plate and the surface of the hinge is more stable.

[0015] Further, the connecting pin is in the shape of a whole cone, which includes a small end and a large end; the large end is fixedly connected with the cover plate and is in interference fit with the threaded hole.

[0016] By using the above scheme, the small end is provided to facilitate the insertion of the connecting pin into the threaded hole, and the large end is in interference fit with the threaded hole to connect the threaded hole with the connecting pin.

[0017] Further, the bottom wall of the cover plate is provided with a guide cylinder, which is sleeved outside the large end of the connecting pin, and the small end of the connecting pin protrudes outside the guide cylinder; the bottom wall of the cover plate is recessed to form an annular groove, and the guide cylinder can slide into the connecting groove; an elastic member is arranged in the annular groove, one end of the elastic member is fixedly connected with the bottom wall of the annular groove, and the other end is fixedly connected with the top wall of the guide cylinder; the caliber of the guide cylinder is smaller than the caliber of the threaded hole.

[0018] By using the above scheme, the elastic member pushes the guide cylinder to move close to the small end of the connecting pin in a natural state, and in the maximum elongation state of the elastic member, the guide cylinder sleeve is sleeved on the periphery of the large end of the connecting member; the guide cylinder is used to tighten the connecting pin, so that when the bottom wall of the guide cylinder abuts against the hinge during the process of covering the surface of the hinge with the cover plate, it will gradually shrink into the annular groove, and at this time the elastic member is in a compressed state; during the process of gradually shrinking the guide cylinder into the annular groove, the connecting pin is gradually inserted into the threaded hole; because the guide cylinder is provided, the guide cylinder can first tightly cover the connecting pin, so that the diameter of the large end face of the connecting pin is reduced, which facilitates the insertion into the threaded hole; after being inserted into the threaded hole, the connecting pin gradually expands due to the willingness of its own material, so as to be in interference fit with the threaded hole.

[0019] Further, the bottom wall of the guide cylinder is provided with an enlarged plate, which is arranged around the bottom wall of the guide cylinder, and the enlarged plate is used to increase the contact area of the guide cylinder and the upper surface of the hinge.

[0020] By using the above scheme, the enlarged plate is used to increase the contact area of the guide cylinder and the upper surface of the hinge, so as to facilitate the movement of the guide cylinder into the annular groove when the cover plate is pushed towards the surface of the hinge.

[0021] Further, the outer side of the annular groove is provided with a containing groove, the containing groove is consistent with the shape of the enlarged plate, and the containing groove is used for bearing the enlarged plate; a third adhesive layer is arranged between the containing groove and the enlarged plate, and the third adhesive layer locks the plug-in state of the enlarged plate and the containing groove after the enlarged plate is retracted into the containing groove.

[0022] By adopting the above scheme, because the containing groove is arranged, the enlarged plate is completely retracted into the containing groove after the connecting pin is completely inserted into the threaded hole, and the arrangement can reduce the gap between the cover plate and the hinge surface.

[0023] Further, a sliding layer is arranged between the guide cylinder and the connecting pin, the sliding layer is attached to the inner wall of the guide cylinder, and the sliding layer is used for reducing the friction between the guide cylinder and the connecting pin.

[0024] By adopting the above scheme, the sliding layer is arranged to reduce the friction between the guide cylinder and the connecting pin, so that the guide cylinder is conveniently retracted into the annular groove.

[0025] Further, the sliding layer is a polytetrafluoroethylene coating.

[0026] By adopting the above scheme, polytetrafluoroethylene has an extremely low friction coefficient, usually between 0.04-0.15, which makes the friction between two objects coated with this coating very small, and sliding is easily achieved.

[0027] In summary, the present application has the following technical effects:

[0028] 1. By arranging the cover plate, the cover plate arranged on the hinge can cover the upper surface of the hinge, thereby shielding the screw, so that the upper surface of the hinge is smooth, which not only maintains the appearance of the hinge, but also isolates the screw from direct contact with air within a certain range, thereby slowing down the oxidation speed of the screw;

[0029] 2. By arranging the connecting pin, the connecting pin and the threaded hole can be connected, and because the connecting pin is connected with the cover plate, the connection area of the cover plate and the hinge surface is increased, so that the connection of the cover plate and the hinge surface is more stable;

[0030] 3. By arranging the containing groove, when the connecting pin is completely inserted into the threaded hole, the enlarged plate is completely retracted into the containing groove, and the arrangement can reduce the gap between the cover plate and the hinge surface.
